Master Flow

Whatsapp Order

Master Flow is a high-performance concrete plasticizer and superplasticizer designed to improve the workability and flow of concrete mixtures without increasing water content. It enhances concrete slump, making placement and compaction easier, especially in large pours or complex formworks. Master Flow promotes better dispersion of cement particles, leading to improved strength development, reduced bleeding, and increased durability. It is widely used in ready-mix concrete, precast elements, and infrastructure projects to achieve superior surface finish and mechanical properties.
